To @ZZ whom it may concern:

Beit known that I, GEORGE H. REYNOLDS, a citizen of the United States, residing at Mansfield Depot, county of Tolland, and State of Connecticut, have invented a new and useful Improvement in Cooling or Radiating Mechanism, of which the following is a description.

This invention relates, generally, to cooling or radiating mechanism, and particularly to cooling chambers or cylinders for ice-niaking machines or refrigerating apparatus, such as forms the subject matter of my application, Serial Number 341,931, iled Oct. 31, 1906, of which this application is a division.

Among the objects of my invention may be noted the following: to provide a cooling or radiating mechanism which is capable of receiving and distributing Within its compass an immense volume of iiuid under compression so as to enable said gas to be cooled and delivered for use to provide a cooling or radiating mechanism so constructed as to enable it to have a place in a compact system of refrigeration capable of installation on shipboard, in restaurants and other places Where economy of space is an important object; to provide a cooling mechanism specially adapted for combination withother elements of a compact refrigerating apparatus; to provide a cooling cylinder wherein the radiating surface, which may be engaged by the cooling medium, has been brought to a maximum in a minimum space, with a maximum efficiency; and to provide a simple, compact, efficient and easily constructed cooler or radiator for the purposes to which it may be adapted.

Vith the above objects in view, together With others Which may be set forth during the course of this description, my invention consists in the parts, features, elements and combinations of elements hereinafter described and claimed.

In order that my invention may be clearly understood, the accompanying drawings are made a part hereof, and therein: Figure 1 represents, diagrammatically, all the essential parts of a refrigerating apparatus in connection with Which my cooler or radiator is shown, as an example of its application or adaptability g Fig. 2 is a top plan of the apparatus shown in Fig. l; Fig. 3 is a rear side elevation of the apparatus of Fig. 2; Fig. 4 is a vertical, longitudinal section of the cooling cylinder Fig. 5 is an elevation of the inlet end of the cooling cylinder, the head being removed; and Fig. 6 is a sectional detail illustrating the manner in which the coils of the cylinder are combined or coupled.

In order that my invention may be clearly understood and especially its mode o1 application to some known system wherein its functions become definite, I have shown the same as a part of a refrigerating apparatus, which latter I will first describe generally with reference to Figs. 1, 2 and 3.

llater, which is employed as a cooling medium for the gas, is conveyed to the apparatus by connection with any suitable Water main, plug or spigot through the water inlet pipe 1, the pump 2 beinO employed for causing the proper circulation o1 the water through the apparatus; the Water after leaving the pump being driven through the pipe connection 3 to the compressor 4, and from the latter through the pipe 5 to the cooling tank or radiator 6and from the latter through the pipe 7 to the sewer or any suitable drain. The compression cylinder or tank 4 has combined therewith a primer pump mechanism, which is illustrated in the diagram only by the small pipe connection 8 tapped into the return pipe of the air circulating system at the point indicated by 9, the other end of said primer pump being tapped into the compression cylinder at 10, in order to illustrate that the compression cylinder' may be primarily supplied with air, and thereafter constantly supplied with air in order to keep up the volume of gas or other circulating medium. The air or gas on leaving the compression tank passes through the pipe or conduit 11 into the cooling or radiating tank 6, and through the coils or pipes contained therein, passing therefrom through the conduit 12 to the expansion cylinderv 13, thence passing through the conduit 14 through the cold room or other place or point of refrigeration indicated in the diagram at 15. After accom plishing this work in the cold room, the air or gas passes through the return conduit 16 to the compression cylinder Where it is again comlpressed and compelled to perform its wor r.

Viewing Figs. 2 and 3, the juxtaposition of the several parts of the apparatus and the relation of the same to my cooling or radiating mechanism, as contemplated by my invention, and the manner in which the several mechanisms are combined in order to form a simple and compact refrigerating apparatus, will be readily understood; and particularly referring to these figures, the main frame is indicated by 17 and centrally supports the framing 18 upon which is mounted a motor 19. The frame 17 also supports pillow blocks or journal bearings 20 1n which the driving shaft 21 is supported and operates, which shaft carries at one end the driving wheel 22, which may, if desired, be a sprocket wheel driven by a sprocket chain 23. At one end the main frame 17 supports or is formed into the frame structure 24 carrying the compression chamber 4 and upon said frame structure 2, a superstructure 25 is mounted which carries the cooling or radiating mechanism 6. At the opposite end of the main frame 17, the latter supports a frame structure 26 which carries the expansion chamber 13, and its allied valve mechanism.

Generally speaking, the water which is employed as the cooling medium for the gas is pumped or forced into the jacket or water space of the compression chamber by any suitable means, and after circulating around the compression cylinder, is delivered, or passes, to the cooling or radiating chamber through the conduit 5, entering said chamber, or tank, see Fig. 4, at the bottom thereof through the inlet 27 and filling said tank and freely circulating among the air-coils thereof, and passing out said cooling tank at the top thereofl through the passage 28, and from thence through the conduit 7 to the sewer or other waste. The cooling tank, shown in its details inFig. 4, consists of the cylinder 6 having bolted thereto, at one end, a head 29 and at the other end a head 30, each of these heads being convexed so as to give strength and rigidity thereto and, incidentally, so as to enlarge the space in the tank 6. The head 29 is provided centrally with a hub affording a seat 31 for the centrally-disposed, hollow journal or support 32 of a mass of air-coils, presently described, said journal being extended into the screw-threaded shaft 33, passing through an aperture in the seat-hub 31 and having a nut 34 turned thereon to clamp the said journal in place in its seat. The opposite cylinder-head 30 is provided with the centrally-perforated hub 35 for the reception and support of the end of the central pipe 36. The cylinder-head 30, near the bottom of the cylinder, is provided with the inlet 37 for the air or gas, said inlet being formed so as to provide a seat and support for the head 38 of the gas-coils or pipes previously referred to. These pipes consist of the outer series of large coils 39, the intermediate smaller coils 40, and thinner coils 41, which are still smaller. These coils are arranged so as to nest one within the other, as shown in Fig. 4, and are preferably held in position and combined for strength and stability by means of clamping and holding bands 42, which partially encircle each coil in a given set, and the parts of which bands are clamped together between the coils of each set bybolts 43, each having a head 44 at one end and the washer 45 and nut 46 at the other end, the said head and washer being curved on their innerfaces so as to correspond with the curvature of the bands between the coils, which curvature is given to said bands in order that they may partially conform to the periphery of the coils at opposite sides of the latter. By thus binding the coils together in sets, as shown, great strength is added, vibration' is eliminated, expansion to a considerable extent is overcome, and a solid and compact structure is produced. At one end, the several coils terminate in the head 38, which forms the generalinlet for the passage of gas, and which is seated in the hub 37 of the cylinder head 30, as previously described. At the other end, the coils terminate in the hollow journalhead 32 resting, as before described, in the central seat 31 of the cylinder-head 9, and which is laterally extended to provide an interiorly screw-threaded portion for connection with the screw-threaded end of the curved central pipe 36 extending centrally and longitudinally of the mass of air-coils.

This pipe is given the sinuous forni shown, so as to enable the same to expand and contract without creating undue pressure upon, or otherwise injuriously affecting, the two heads of the cylinder, it being obvious that, by giving the said pipe the several bends shown, any expansion or contration of the metal of the pipe will necessarily exert substantially no effect upon the said heads of the cylinder 6, the said heads thus not being moved in their relation to the cylinder and there being, in consequence, substantially no strain upon the bolts securing the heads to the cylinder. It will now be obvious that the air, after leaving the compression cylinder, will occupy considerable time in passing through the coils and out of the cooling cylinder, and will be exposed, by reason of the multiplicity of coils, and their disposition, for a long period of time to the cooling effects of the water in the tank. Furthermore, by nesting the several air-coils as described, the latter are given a tremendous radiating surface and enable the water to circulate freely between and around them for the purpose of effectively cooling the air contained in them. The air, after passing through the several coils, enters the central longitudinal pipe 36 and passes from the cooling-tank through the conduit 12 to the expansion cylinder, Where it is expanded and additionally cooled for service.

As previously stated the motor 19, drives the shaft 21, a pulley or sprocket-Wheel 47 being carried by the shaft of the motor for the purpose, the same driving the sprocketchain or belt 23. The other end of the shaft 21, is provided with an eccentric 48, imparting motion to the pitman 49, which rocks the crank 50, carried by a shaft 51, in turn operating a valve-mechanism in the expansion chamber 13, the frame of Which is indicated by 52 and is carried on top of said chamber 13, The outermost end of shaft 21, carries a pulley or sprocket-Wheel which drives a chain 53, for actuating the pump 2.

Having thus described my invention What I claim and desire to secure by Letters Patent is:

1. A cooling apparatus comprising` a cooling chamber having disposed therein a plurality of nested, helical tubes, which increase in diameter from the inner to the outer helix,

f means for joining the tubes of each helix Within the chamber at opposite ends, and means for supporting said tubes by said {oining means at opposite ends of the cham- 2. A cooling apparatus comprising a cooling chamber, and a plurality of coiled tubes contained therein the terminal of Which tubes is composed of a centrally-disposed sinuous outlet tube extending through the center of said coils of tubes and supported at opposite ends in the opposite ends of the cooling chamber, whereby strain upon said ends is avoided.
